TPS61041: Can it be configured as flyback for 200Vout?

Part Number: TPS61041
Other Parts Discussed in Thread: LM3478,

Is it possible to use the TPS6104x in a flyback configuration, similar to this?

We need 60-200V range for APD bias. Load current is <1mA. Output ripple is not a major concern, we can filter higher harmonics with a 2nd stage RC filter.

The transformer would be 1:10 ratio, something like TDK ATB Series.

    TPS61041 is an integrated boost conveter. Its internal MOSFET VDS voltage is less than 30V, so it is not fit for the application. Suggest you use a controller like LM3478 with external MOSFET to realize the function. But make sure the Vin pin voltage should be less than 40V
